    Design REF200
    SBVS020B – SEPTEMBER 2000 – REVISED JULY 2015 REF200 Dual Current Source and Current Sink
    1 Features 3 Description The REF200 combines three circuit building-blocks
    on a single monolithic chip: two 100-ВµA current
    sources and a current mirror. The sections are
    dielectrically isolated, making them completely
    independent. Also, because the current sources are
    two-terminal devices, they can be used equally well
    as current sinks. The performance of each section is
    individually measured and laser-trimmed to achieve
    high accuracy at low cost. 1 Completely Floating: No Power Supply or Ground
    High Accuracy: 100 ВµA В±0.5%
    Low Temperature Coefficient: В±25 ppm/В°C
    Wide Voltage Compliance: 2.5 V to 40 V
    Includes Current Mirror 2 Applications The sections can be pin-strapped for currents of 50
    ВµA, 100 ВµA, 200 ВµA, 300 ВµA, or 400 ВµA. External ...

    Single-Supply, Low-Power Measurements Of Bridge Networks
    Bridge sensor measurements often need to be made in systems operating on a single 5V power supply. An OPA1013 dual op amp along with a REF200 current source, makes an excellent bridge measurement system which features low power single-supply 5V operation and immunity to power supply variations. One OPA1013 dual op amp is used as a two-op-amp instrumentation amplifier. A second OPA1013 is used with

    Diode-Based Temperature Measurement
    Diodes are frequently used as temperature sensors in a wide variety of moderate-precision temperature measurement applications. The relatively high temperature coefficient of about -2mV/В°C is fairly linear. To make a temperature measurement system with a diode requires excitation, offsetting, and amplification. The circuitry can be quite simple. This Bulletin contains a collection of circuits

    Make A Precision Current Source or Current Sink
    The precision current source and sink are based on the new REF102 10.0V voltage reference. With 2.5ppm/В°C VOUT drift, and better than 5ppm/1000hrs long-term stability, this buried-zener-based voltage reference offers the best performance available from a single-chip voltage reference today. The REF200 uses a band-gap type reference to allow low-voltage two-terminal operation. This m

    Boost Instrument Amp CMR With Common-Mode Driven Supplies
    Ever-increasing demands are being placed on instrumentation amplifier (IA) performance. When standard IAs can not deliver the required performance, consider this enhanced version. Dramatic performance improvements can be achieved by operating the input amplifiers of a classical three-op-amp IA from common-mode driven sub-regulated power supplies.
